Federico Kirschbaum has reported a vulnerability in Barracuda Spam Firewall, which can be exploited by malicious people to conduct script insertion attacks.
Input passed via the username when logging in to the Web Administration Console is not properly sanitised before being displayed in the Monitor Web Syslog screen. This can be exploited to execute arbitrary HTML- and script code in an administrative user's browser session in context of the web administration interface.
Successful exploitation requires that the target user has opened the Monitor Web Syslog screen.
The vulnerability is reported in Barracuda Spam Firewall firmware 220.127.116.11. Other versions may also be affected.
Solution: Update to firmware version 18.104.22.168.016.
